🎯 Target Return Calculator
Set your target Cash-on-Cash return, then let the tool reverse-calculate what one key variable needs to be to achieve it — using all other inputs from the Analyze tab.
How it works: All other inputs are taken directly from your current Analyze tab entries. The solver uses binary search (300 iterations) to find the exact value that produces your target CoC. After finding the value, you can click "Apply to Form" to load it directly into the Analyze tab.
💵 Payment Budget Solver
